Chrome: The web provides tons of great written content, but that can get a little overwhelming when you're not in the mood to read all day long. Announcify is a browser extension for those times when you'd rather just listen. All you have to do is browse to any article and click the Announcify button.

As you can see from the screenshot above, Announcify still shows you the text it's reading to you in a more readable format. It also blurs out everything but the paragraph it's reading to make it much easier to follow along. You can set the voice that reads the text, its speed, and its pitch so you can hear the articles the way you want. Announcify is free and really handy for those times when your eyes are too tired but you're still eager to read.
